There’s nothing quite as frustrating as an AC that won’t blow cold air on a hot Toledo summer day. Instead of working up a sweat, let’s walk through the most common reasons your AC may not be blowing cold air and what you can do about it.
Reasons Your AC May Not Blow Cold Air
AC problems can have a variety of causes, some of which are simple enough to troubleshoot at home. Others require professional AC repair, and knowing the difference will save you time and stress.
Clogged Air Filter
A dirty or clogged air filter restricts airflow, making it harder for your system to cool your home effectively.
What you can do: Check your air filter and replace it if it looks dirty or hasn’t been changed in the last three months.
Call for help if: The air still isn’t cool after replacing the filter, or if the system keeps shutting off unexpectedly.
Thermostat Malfunction or Incorrect Settings
Sometimes, the issue is as simple as an incorrect setting or a thermostat that isn’t working properly.
What you can do: Make sure the thermostat is set to “cool” and that the temperature is lower than the current indoor temperature. Check the batteries if it’s not responding.
Call for help if: The thermostat is unresponsive or fails to communicate with the system.
Clogged Condensate Drain
Your AC removes humidity as it cools, and that moisture needs somewhere to go. A clogged drain line can cause your system to shut down or behave erratically.
What you can do: Look for signs of water near your indoor unit or around the drain pan. Some homeowners can clear clogs with a wet/dry vacuum.
Call for help if: You notice water damage or mold, or the system shuts down entirely.
Low Refrigerant Levels
Refrigerant is what actually cools the air in your AC system. If levels are low, there may be a leak.
What you can do: Unfortunately, this isn’t something you can fix yourself — AC refrigerant systems are sealed and require professional handling.
Call for help if: Your system is running constantly but never gets cool, or you hear hissing sounds near the unit.
Ice on the Evaporator Coil
A frozen coil blocks airflow and prevents your AC from cooling your home. This is often linked to airflow issues or refrigerant problems.
What you can do: Turn off the AC and switch the fan to “on” to allow the coil to thaw. Check your air filter and the airflow around vents.
Call for help if: Ice keeps returning or you suspect a deeper issue like low refrigerant.
Faulty Compressor
The compressor is like the engine of your AC. If it fails, your system may blow warm air or stop working altogether.
What you can do: There’s not much a homeowner can safely do here.
Call for help if: The system turns on but doesn’t cool, or makes loud, unusual noises.
Tripped Breaker
Sometimes, the breaker for your AC may trip, cutting off power to the unit.
What you can do: Check your breaker box and reset the switch if needed.
Call for help if: The breaker keeps tripping repeatedly, which may indicate an electrical issue.
How To Prevent AC Issues
Routine AC maintenance is the best way to avoid unexpected breakdowns. A professional tune-up each spring can catch small issues before they turn into big problems, improve energy efficiency, and extend the life of your system.
During a maintenance visit, our technicians will clean components, check refrigerant levels, inspect the electrical system, and make sure your AC is running safely and effectively.
